Longitudinal effects of physical activity on self-efficacy and cognitive processing of active and sedentary elderly women (original) (raw)

Previous studies support that regular physical activity in aging contributes as a protective factor against cognitive decline and improves mood states. However, there is a lack of longitudinal studies in this area. Objective: To observe possible changes in cognition related with physical activity. Methods: This study reassessed, after one-year period, 31 elderly women divided into two groups, sedentary versus active, using behavioral scales and cognitive tests. Results: The active group exhibited significantly enhanced performance in general cognitive function, particularly on tasks of episodic memory and praxis, and also on the mood states scale compared to the sedentary group. The active women also reported higher self-efficacy. Conclusion: Long-term physical activity promoted improvement on quality of life in the elderly women.
The Effects of Physical Activity and Sedentary Behavior on Cognitive Health in Older Adults
Journal of Aging and Physical Activity, 2005
Background: This study examined the effects of cognitive restructuring techniques on self-efficacy and physical activity. Methods: An intervention was designed to increase the self-efficacy of 61 older adults and then evaluated to measure the effectiveness of the intervention. A pretest/posttest analysis of variance was conducted to look for differences in knowledge, attitudes, physical activity, and self-efficacy.

OBJECTIVES: To examine the hypothesis that changes in self-efficacy and functional performance mediate, in part, the beneficial effect of physical activity on functional limitations over time. DESIGN: Prospective, observational study. SETTING: Community-based. PARTICIPANTS: Two hundred forty-nine communitydwelling older women. MEASUREMENTS: Participants completed measures of self-reported physical activity, functional limitations, and self-efficacy. Four measures of physical function performance were also assessed. Measures were completed at baseline and 24 months. Data were analyzed using a panel model within a covariance modeling framework. RESULTS: Results indicated that increases in physical activity over time were associated with greater improvements in self-efficacy, which was associated in turn with improved physical function performance, both of which mediated the association between physical activity and functional limitations. Fewer functional limitations at baseline were also associated with higher levels of self-efficacy at 24 months. Age, race, and health status covariates did not significantly change these relationships. CONCLUSION: The findings support the mediating roles of self-efficacy and physical function performance in the relationship between longitudinal changes in physical activity and functional limitations in older women.
Physical activity and functional limitations in older women: Influence of self-efficacy
2006
Abstract This study examined the role of self-efficacy and physical function performance in the relationship between physical activity and functional limitations. Older women (age, M= 68.2 years) completed measures of physical activity, self-efficacy, physical function performance, and functional limitations at the baseline of an ongoing study. Analyses indicated that physical activity was associated with self-efficacy for exercise, efficacy for gait and balance, and physical function performance.

There are consistent associations between physical activity and self-perceived health. However, it is not clear whether associations between self-perceived health and participation in physical activity could be accounted for by associations with cognitive function. In the present study, we examined whether associations between physical activity and cognitive functioning could explain the variability between physical activity and self-perceived health. A sample of 204 older adults performed three cognitive tests selected from the Vienna test system battery: The Determination, Cognitrone, and Visual Memory tests. These tests measure general processing speed, attention, and visual memory, respectively. Participants also completed the 12-item Short Form Health Questionnaire SF-12 to measure perceived health, and the Physical Activity Survey for the Elderly to measure physical activity. Linear regressions and the PROCESS macro for SPSS were used to test our hypotheses. Consistent with ou...
Physical activity and quality of life in older adults: influence of health status and self-efficacy
2006
Background: Physical activity has been positively linked to quality of life (QOL) in older adults. Measures of health status and global well-being represent common methods of assessing QOL outcomes, yet little has been done to determine the nature of the relationship of these outcomes with physical activity. Purpose: We examined the roles played by physical activity, health status, and self-efficacy in global QOL (satisfaction with life) in a sample of older Black and White women.
Pathways from Physical Activity to Quality of Life in Older Women

Background-In spite of consistent evidence to suggest that being more physically active is associated with enhanced quality of life (QOL), there have been remarkably few attempts to determine the possible underlying mechanisms in this relationship.
Physical activity and psychological well-being in older women
Women's Health Issues, 1997
Physical activity clearly has benefits for the health and well-being of women and men of all ages, and activity may well be particularly beneficial for older individuals. Physical gains and health benefits of activity are well documented, and physical activity is identified as a health promotion priority area by the U.S. Dept. of Health and Human Services. 1
A Prospective Study of Physical Activity and Cognitive Decline in Elderly Women
Archives of Internal Medicine, 2001
Background: Several studies have suggested that physical activity is positively associated with cognitive function in elderly persons. Evidence about this association has been limited by the cross-sectional design of most studies and by the frequent lack of adjustment for potential confounding variables. We determined whether physical activity is associated with cognitive decline in a prospective study of older women.
Long-term maintenance of exercise, self-efficacy, and physiological change in older adults
1993
Abstract The present study documents the maintenance of exercise participation, self-efficacy, and physiological change in older adults at 9-month follow-up to a 5-month structured exercise program. Males and females (mean age= 54 years) completed graded exercise testing, body composition, and physical performance testing at the end of and 9 months after cessation of an exercise program.
